SPECIFICATIN formng part of Letters;Patent No. 652,012, dated J une 19, 1900. Application filed J'anuary 8, 1900. Serial No. 793. (No modal.)

T0 al w/wm izfi may concern- Be it known thatI, GEORGE A. BAKER, a citizen of the United States of America, and a resident of Melrose, county of Middlesex, in the State of Massachusetts, have inventedcertain new and useful Impiovements in Binnaoies and Binnacle-Lamps, of which the following is a specification.

My invention relates to improvements in binnacles and binnacle-lamps wherein the air is indirectly admitted to the hood of the lamp, passing upwardly, feeding the fiame, and finding egress at the top of said hood, while the latter is constructed in a manner to exclude direct air-draft to the dame, receiving only the indirect currents of air from the binnacle interior.

The objects of my improved invention are to secure a steady flame, the non-liability of extinguishing the lamp from direct draft, insuring better illumination of the compass within the binnacle, the introduction indirectly of oxy'gen through the binnacle to the burner, thorough ventilation of the lamphood, durability and eficiency in operation, and in other improvements hereinafter specified, and more fully set forth in the appended claims.

A more specific description of my improved invention will be observed in the annexed drawings, forming a part of this specification,

in which- Figure 1 is a view in perspective of my im proved lamp attached to the binnacle in its operative assemblage, Fig. 2 being an elevation of the side of the binnacle supporting the hood and lamp. Fig. 3 is a vertical longitudinal section through lamp and binnacle as appears when organized.- Fig. 4 exhibits an elevation of the side of the hood, Fig. 5 being a similar view of the front of the same. Fig. 6 illustrates the air-excluding shield in elevation, Fig. 7 showing a similar elevation of the re= verse side. Fig. 8 denotes the lamp in elevation removed from the hood. Fig. 9 is a simi lar view of the reverse side, and Fig. 10 an enlarged view in section of the base of the lamp With the air-excludin g shield in position to shut off air to the interior of the hood.

Oorresponding letters designate similar fea tures throughout the several views.

Referring to the drawings, A denotes that portion 'of the binnacle supporting the hood,

receive the shoulders D D of the [lange D,

forming an integral part of the hood F. The lower perimeter of said fiange is perforated With a series of air-ports E, communicating to the binnacle through the aperture B and which permits the air to be drawn from thenee into the hood F, where it furnishes oxygen to the lamp-fiame, following the direction of arrows C 0, Fig. 3, the heated,air escaping from the annular'series of ventilating-slits G above the cone F, which protects the fiame from incoming currents of air (if such there should be) entering through said slits. These are vertically placed near the top of the cylindrical hood F, one of the sides of each bein g curved slightly inward, as at G, to form openings for the egress of heated air. The base of said hood F is further integrally provided at the bottom With the lamp-retaining ring H, which is furnished With the ordinary bayonet-slots I I, one upon each side, to support the lamp when in operative position.

J designates the air-excluding shield or ring, this being an essential feature of my improvement, which is fitted closely over the base H, the vertical slotsK K before the final adjustment of the 1amp being each in alinement With the bayonet-slots I I. When the lamp is fully adjusred and secured to the base Il of the hood F, by turning to the right the wick-adjusting stem L and stem L to the left, each being within the alined slots I and K, obviously carries said shield J around the stationary ring H to the limit of the bayonetslots I I, when it would appear as in Fig. 10, eifectually preventing the air from admission to the flame, as would occur if said slots I I were left open. I thus secure a steady light which is sufficiently nourished by the indirect admission of air to the hood,as previously described, the greater or less volume of which is governed by the size and number of said air-ports E.

Having described the nature and construction of my improved invention, I desire not to .be confined t0 a close interpretation thereof, but may employ such fair equivalents there for as wil1 embodythetrue spirit of 111 y inven, tion. Having deseribed my invention, I desire to secure by Letters Patent of the United States and c]aim 1. A binnacle having an aperture for the admission of air, proViddwith n1eans f0f the support of the assembled hood and Iamp, in
